Isobenzofuranone and chromone containing a cyclic ketone or lactone moiety as effective acceptor building units to construct donor–acceptor TADF emitters. Blue TADF-OLEDs utilizing these emitters exhibit external electroluminescence quantum efficiencies of up to 16.2% and extremely low efficiency roll-off even at practical high luminance. The current findings open new avenues for designing practically usable high-performance blue TADF emitters with simple molecular structures.
